Electronic immobilizer

The engine immobilizer, a security feature, helps to prevent car thefts by ensuring only the correct keys can be used to start the car. This is accomplished by checking the code on the car key with the one stored in a computer. If the codes are compatible, the engine will be allowed to begin. This method has been used for more than 20 years and has contributed to decrease the theft of vehicles. It's also a great way to prevent hotwiring, which is the act of bypassing the ignition switch by connecting wires between the ignition coil and the fuel pump relay.

The immobilizer is a part of the key fob or key which contains the transponder chip. The chip transmits a passcode from the key fob or key to the immobilizer system of the vehicle, which is integrated into the PCM (or BCM), instrument cluster and smart junction boxes or other modules. The immobilizer unit then verifies the passcode and allows the engine to start if it is correct.

Modern keys and transponder chips use a cryptographic algorithm to ensure that the code is only transmitted once and only to the authorized key fob or key. These cryptographic algorithms are designed to be difficult for hackers to decode. This technology guards against remote key replication which is common when cars are taken.

It may also disable fuel pumps, ignition coils or injectors based on the type of engine that is installed in your vehicle. The engine will start for a few seconds and then shut down and it will be impossible to drive the vehicle away.

Immobilizers are an excellent security device that has helped reduce vehicle thefts by blocking hot wiring. However, it is not foolproof, and many thieves have devised ways to get around the immobilizer. These methods include using a computer to decode the algorithm. This can be done using a program that is specifically designed for this purpose.

Another option is to use a device to change the code on the transponder chip or key. This can be done by using a device known as a "transponder reader" which can be purchased online. These tools don't always work however, they can be useful in some cases.
